The optical central area has a vision-correcting function, the optical buffer area is formed by an asymmetric curvature focal point, and the optical peripheral area extends to the edge of the lens. The overall design results in extremely low contrast of artificial light, and the image point design ensures that the light path falls in front of the retina.

Benefits of technology

By reducing the contrast of artificial light entering the eye, it controls the progression of myopia, inhibits the growth of the axial length of the eye, and relieves eye strain.
